TIMOTHY LYnoN, or BALTIMORE, MARYLAND.

WALL AND CEILING STRUCTURE.

Application ed January 19, 1922. lSerial No. 530,325.

To all whom t may concern:

Be it known that TIMOTHY LYDON, a citizen of the United States, residingat Baltimore, in the State of Maryland, has invented certain new anduseful Improvements in Wall and Ceiling Structures, of which thefollowing is a specification.

This invention relates to improved means for securing tiles, slabs orplates in place in l0 the formation of ceilings or walls.

The term tiles as herein employed by me is used in a broad sense in thatit is applied by me to any wall or ceiling element which is molded orshaped into a tile, slab or plate and is not necessarily a bakedproduct.

The object of the invention is to provide improved means whereby tiles,slabs or plates may readily be secured to overhead joists to form aceiling or to studding in the formation of a walk-the structure beingsuch that unskilled labor may be employed and the tiles readily appliedregardless of the irregularity in the spacing of the joists or studding.

With the above and other objects in view the invention is illustrated inthe accompanying drawings, wherein,"

Fig. 1. shows a sectional perspective view of a series of joists withiiooring on the upper side and with my improved tile securing devices onthe lower side thereof.

Fig. 2. illustrates a cross-sectional view of the same,-the sectionbeing taken on the line 2-2 of Fig. 1 to which the facing slabs havebeen added.

Fig. 3. shows, in perspective, a series of tile supporting stripsr andtiles` sustained thereby as viewed from the upper side,.- the joistsabove being omitted.

Fig. 4. illustrates a side edge view of a plulrality of tiles to showhow they lap.

Fig. 5. shows an enlarged detail of one of the tile supporting stripswith a tile at each side thereof and also shows the means for securingthe strips in place.

Fig. 6. illustrates one of the detached tile-supporting strips.

Fig. 7 shows one of the tiles in perspective.

Fig. `8. illustrates a sectional detail through the tile, in alengthwise direction or from end to end, and

Fig. 9. shows a cross-sectional detail through thetile from one sideedge to the other.

Referring to the drawings the numeral 12, designates a series ofspaced-apart supports such as joists or, in the case of a wall, a seriesof studs which in practice are presumably spaced at equal distancesapart, but in reality are frequently spaced unequally. In some instancesthe unequal spacing between the centers of the joists or studs is sopronounced that it is impracticableto attach tiles, slabs or platesdirectly to those joists or studs, but in accordance with my inven tionit isimmaterial whether the joists or studs be equally or unequallyspaced.

In carrying out my invention I ,employ what I term a series ofsupporting strips or rails 13. These strips or rails as best shown inFig. 6 of the drawings have fiat parallel inner and outer faces 14: and15 respectively,-the outer face being wider than said inner face so asto form longitudinal side anp'es 16 at opposite sides of each strip.

The supporting strips ory rails 13, are seated with their innerInarrower faces 14: against the joists or studs and extend at rightangles to the latter so that each strip will extend across a series ofjoists or studs, as clearly shown in Fig. 1 of the drawing.

These strips or rails 13 are equally spaced and are rigidly secured tothe joists or studs they cross by means of nails or equivalentfastenings 17, as shown in Fig. 5 of the drawings. Y

In some instances I have found it desirable to lay a brace strip 18,againsty the outer wider face 15 of each rail 13 and have the fastening17 extend through the latter, then through the rail and onto the joistor stud 12. This brace plate by extending across the outer wider face ofthe rail serves to support the rail at the opposite edges where the sidefianges 16 are located, which is very de sirable as will presently beseen.

In the case of a ceiling structure the upper side of the joists willsustain the flooring 19 as shown in Figs. 1 and 2.

In carrying out my invention I utilize a special construction of tile,slab or plate, 20, a form of which is shown in Figs. 7-8 and 9 of thedrawings to which attention is now directed.

' For the sake of brevity I shall hereinafter make use of the singleexpression slab, which however is to be construed as meaning acomparatively thin tile, slab or plate.

- 1 the outer surface 22. At the opposite end,

the slab has a flange 25, which is flush with the outer surface 22 andwhich projects beyond the inner surface 21.

By reference to Figs. 7-8 and 9 it will be noted that the flanges 23-2eand 25 are each half the thickness of the slab so that if anunderlapping flange 25 on one end of a slab is fitted against anoverlapping flange 24 on the end of another slab the two lapped flangeswill together substantially equal the thickness of a slab.

By refer-ring to Figs. 8 and 9 it will be noted that each slab has aplurality of wire strands 26 extending crosswise therethrough and thatthe opposite ends of the wire strands project along the under faces ofthe side flanges 237 all for a purpose presently to be explained. Y

TheY supporting rails or strips 13 are so spaced with respect to eachother that a slab 2O may be placed between them with the side flanges 23of the slab lapping the sideflanges 16.0f the rails, as clearly shownvin Eigs. 3 and of the drawings.

ln the ease of a ceiling structure the flanges 23l of the slab will seatin the flanges 16. of the rails at opposite sides of it and thuslsustainthe slab between the two rails.

lt will also be noted thaty as the ends of theY cross-wires 26 projectalong the under side of the slab flanges 23 that they will reinforcethose flanges at the point of suspension.

As the weight of the slabs is directly on the. rail flanges 16 anytendency of those flanges to split or break olf is overcome by thefbracestrip 18.

By reference to Fig. 5 it will be noted that when the slabs arev seatedon the rail flanges 16 their inner faces 21 `will be slightlyspacedfrorn the lower facesof the iinish,-this however being immaterialto my invention.

'llhen the slabs are in place their ends will be engaged by the endflange 2e of one lapping the end flange of the next so that an endsupport will thus be provided between the ends of abuttingslabs.

l-lavingdescribed iny inventiom claim,

1. In a wall or ceiling structure the coinbination with spaced apartsupports of parallel but spaced-apart flanged rails extending at rightangles to and crossing said supports said rails being rigidly securedagainst the said supports, separate slabs each having overhangingside`flanges at two opposite sides vand each slab also-having at one end aflange that is flush with the inner surface 0f theslab while at theopposite end each slab has another flange which is flush withl the outersurface of the slab whereby to produce an underlapping flange at oneendV and an overlapping flange Vat the opposite end of said slab,-theslabs being supported their sideV Yflanges on the lflangesof the railsand one end of a slab underlapping the slab next t0 it at that end whilethe opposite end vof the saine slab willoverlap the slab next to it saidllatter end Yand the adjacent .ends of two slabs /thereby be broughtinto direct butting and lapping contact one with the other.

2. The combination with spaced apart supporting ineans7 of flanged railssecured to said supporting means and extending crosswise of thelatterfseparate slabs each having side'flanges whichengage and arevsustained by the rail-flanges and said slabs also having an underlappingflange at one end and an overlappingflange at the opposite end wherebyvthe adj acent ends of the several slabs may be lapped and supported atthe. end one by the other.

In testimony whereof l affix` iny signature.
